What does this test measure?

Your result shows whether your blood has IgE to Trichophyton mentagrophytes. A specialist reads it with your symptoms and history as one part of a hives or asthma evaluation.

Trichophyton mentagrophytes-specific IgE
Specific IgE is an antibody the immune system can make against one allergen. This marker measures IgE that recognizes Trichophyton mentagrophytes, a skin fungus that can cause athlete’s foot and ringworm. A level above the lab’s reference range shows sensitization.
Why it’s measured: Checks for IgE sensitization to Trichophyton mentagrophytes in hives or asthma workups.

Questions

No. This test measures IgE to Trichophyton mentagrophytes, a skin fungus that can cause athlete’s foot and ringworm. It does not check for a current skin infection; a healthcare provider looks at the skin or uses other tests for that.

A positive result shows sensitization, which a specialist reads with your symptoms and history.

It is sometimes checked in chronic hives or asthma workups, as one piece of information a specialist reads with your symptoms and history.

A positive result shows sensitization, not that the fungus causes your symptoms, and a negative result does not clear an allergy.

No. Sensitization means your body has made IgE to Trichophyton mentagrophytes. An allergy means that exposure causes symptoms. Many people are sensitized without having symptoms, so a positive result alone does not mean you are allergic.

A negative result does not clear an allergy either. An allergist or other healthcare provider reads your result with your history.
